ROLLER-BEARING.

To all whom it may concern;

Be it known that I, DAvlo L. TSCHANTZ, of

Canton, Stark county, Ohio, have invented a new and useful Roller-Bearing, of which the .following is a full, clear, and exact description, reference being hadto the accompanying drawings, forming part "of this specification, in which the figure is a longitudinal section of a roller-bearing device embodying my invention.

My invention has relation to the class of roller bearings, and. is designed to' provide an improved bearing device of this character, in

V which the parts subject to wear areicapable of being readily removed, and in which provisionis made for adjustment to compensa te for wear.

The present application is an improvement I upon the roller bearing described and claimed bearing as applied to a vehicle wheel and in my fqending application, Serial No. 387,612, ed August 8th, 1907.

The precise nature of theirnprovement will be best understood by reference to the accompanying drawing, in which I have shown the preferred form of my invention, it being premised, however, that various changes may be made in the details of'construction and arrangement without departing from the spirit and scope of my invention.

In the drawing, in which I have'shown my axle, the numeral 2 designates the axle, and 3 the wheel-hub or casing. This hub is formed with the enlarged portions 4 at each end, which form the chambers for the bearings. Each'of these bearings consists of a slee e member 5, which is placed around the axle, and which is formed with an outer double-coned surface, 6 and 7 the two surfaces being inclined at an angle to each other, forming in effect two cones placed base to base but partially'separated by a circumferential groove 8.

9 designates the rollers, which are arranged in two sets, one set bearing against each of the cone faces. .These rollers are mounted in a cage, consisting of the two end rings 10 and 11, and the central ring 12. The gudgeons or journals at the inner ends of the two series of rollers are both mounted in the central ring 12 of the roller cage, and are abutted end to end therein so that the end thrust on any one roller of one set is communicated directly to the adjacent roller in the other set, thus holding the end faces of the rollers out of contact Specification of Letters Patent. Application filed November 27, 1907. Serial No. 404,176.

with the sides of the ring 12 and preventing friction against such ring. The member 12 is preferably of wedge form and engages the groove 8..

13 and 14 designate two cup members, of the bearing. These are each formed at their these two extensions being engaged with each other. The inner face of each cup mem: ber provides a bearing surface wlnch issubcone surface of the sleeve.

screwed upon the threaded end of the axle, and which closes the outer end of the casing. The two cone-sleeves are shown as held at the proper distance apart by a key 17 which is seated in the axle. When the nut 16 is screwed 'up, the outer cone-sleeve is forced back against the key, and all endwise playi of the cones 'revented together with rotation thereof. he inner cone-sleeve seats back against the collar 18.

In the drawing, 1' have shown the outer bearing casing 4 as formed in a separate piece telescopically fitted Within the central portion of the hub 3. The bearings can be readily removed from the bearing casing for renewal or repairs. tion of the cupmembers of each bearing permits said members to be readil and easily adjusted to take up any wear w ich may occur. The entire bearing is simple in its construction, and is extremely efficient in itsoperation.

While I have shown my improved hearing as used for a wheel bearing, it is obvious that 'ing immaterial to the action of the bearing whether the casing member 3 is the rotating member, or whether such casing is stat-lon ary and the part corresponding to the axle is work e ually well in either case. I

It wil be noted that there is no wear whatever either upon the axle or upon the casing, all Wear being taken by the cone sleeves and the adjustable cups.

What I claim is 1. A roller bearing device, having a bear ing containing casing, and a roller bearing contained therein, said bearing consisting of with end and center members and two sets of rollers ournale :11 said end and center it is adapted to a large variety of uses, it be-.

the rotating member, since the bearing will inner ends with a threaded extension'15,

2. A roller bearing device, having a bearing containing casing, and a roller bearing contained therein, saidbearing consisting of a double-cone member, a roller cage provided with end and'center members and two sets of rollers journaled in said endand center 'members and bearing on the cone member, and a double cup member surroundlngtherollers and forming the outer bearing therefor, said" cone-member roller cage, -rollers, and cup-member being removable from the bearing casing: as aunit, said cup-member journaled therein,

being formed in two parts adjustablyconnected; substantially as described.

' 3. A roller bearing device, having an outer casing, a sleeve member formed with two,

oppositely inclined cone surfaces, a roller cage, two sets of'oppositely inclined rollers and a cup member independent of the outer casing and removably said cup-member having op- 4.. A' roller bearing device, having' an' outer casing, .a sleeve member formed with two opposltely inclined cone surfaces, a roller page, -two sets of oppositely inclined rollers ere-- journaled therein, and a cup-member independent of the outercasing and removably surrounding each sleeve, two sets of opposite-1y inclined rollers journaled therein, and adjustable cup-members, said cup-members, roller cages, rollers, and sleevesbei'ng removable as a unit from their respective chambers; substantially as described."

. 6. In a roller bearing device, a casing member having a bearing chamber at each end, a

sleeve in each chamber having oppositely incl ned cone-bearm'g surfaces, a spaclng member between the two sleeves, a roller cage surrounding each sleeve and two sets of 'oppositely inclined rollers journaled therein, and adjustable cup-members, said cup-members, rollerxcages, rollers and sleeves being chambers; substantially as describe -6O removable as a umt from their res ective In testimony whereof, I have hereunto set my hand.
